Summary: This entry is about the Higgs Boson, a fundamental particle in the Standard Model of particle physics that explains how other particles acquire mass.
Overview
The Higgs Boson is a subatomic particle predicted by the Standard Model of particle physics in the 1960s. It is a scalar boson, a type of elementary particle that plays a crucial role in the fundamental forces of nature. The Higgs Boson is responsible for giving mass to fundamental particles, such as quarks and leptons, which are the building blocks of matter. The existence of the Higgs Boson was confirmed on July 4, 2012, at the Large Hadron Collider (LHC) in Geneva, Switzerland.
The Higgs Boson is named after physicist Peter Higgs, who, along with several other physicists, proposed the existence of a field that permeates all of space and gives mass to fundamental particles. This field is known as the Higgs field. The Higgs Boson is the quanta of the Higgs field, and its discovery has confirmed the existence of the Higgs field and the Standard Model of particle physics.
History/Background
The concept of the Higgs Boson was first proposed by Peter Higgs and Felix Bloch in the 1960s. They suggested that a field, now known as the Higgs field, could be responsible for giving mass to fundamental particles. The Higgs field is a scalar field that permeates all of space and is responsible for the mass of fundamental particles. The Higgs Boson is the quanta of the Higgs field, and its existence was predicted by the Standard Model of particle physics.
The search for the Higgs Boson began in the 1980s, with the construction of the Large Electron-Positron Collider (LEP) at CERN. However, the LEP was not powerful enough to detect the Higgs Boson, and the search was continued at the Tevatron at Fermilab. The Tevatron was also not powerful enough to detect the Higgs Boson, and the search was continued at the LHC.
Key Information
The Higgs Boson is a scalar boson with a mass of approximately 125 GeV (gigaelectronvolts). It has a spin of 0, which means it is a scalar particle. The Higgs Boson is a fundamental particle that interacts with fundamental particles through the Higgs field. The Higgs field is a scalar field that permeates all of space and is responsible for the mass of fundamental particles.
The discovery of the Higgs Boson was announced on July 4, 2012, by the ATLAS and CMS experiments at the LHC. The discovery was confirmed by the observation of a peak in the invariant mass spectrum of particles produced in high-energy collisions. The peak was observed at a mass of approximately 125 GeV, which is consistent with the predicted mass of the Higgs Boson.
Significance
The discovery of the Higgs Boson has confirmed the existence of the Higgs field and the Standard Model of particle physics. The Higgs field is responsible for giving mass to fundamental particles, and the Higgs Boson is the quanta of the Higgs field. The discovery of the Higgs Boson has also confirmed the existence of the electroweak symmetry breaking, which is a fundamental concept in the Standard Model of particle physics.
The discovery of the Higgs Boson has also opened up new areas of research in particle physics, including the search for new fundamental particles and forces. The discovery has also confirmed the existence of the Higgs mechanism, which is a fundamental concept in the Standard Model of particle physics.
